(a) What is the difference between adding subscript 2 to the end of the formula for CO to give CO2 and adding a coefficient in front of the formula to give 2CO? (b) Is the following chemical equation, as written, consistent with the law of conservation of mass? 3Mg(OH)2 (s) + 2H3PO4 (aq) ------> Mg3(PO4)2 (s) + H2O (l) Why or why not?
